I have made thee this day a defenced city, etc.
A sure stronghold is God
Though thou shalt be exposed to persecutions and various indignities, they shall not prevail against thee. To their attacks thou shalt be as an impregnable city; as unshaken as an iron pillar; and as imperishable as a wall of brass. None, therefore, can have less cause to apprehend danger than thou hast. The issue, in Jeremiah’s case, proved the truth of this promise; he outlived all their insults; and saw Jerusalem destroyed, and his enemies, and the enemies of the Lord, carried into captivity. (Adam Clark.)
